SHOE-SHANK.

tion, and the object of my invention is to provide animproved methodofsecuring the required stlfness to the shank .portion of the shoe,thereby giving properv sup ort to the arch of the foot, by inserting witin the said shank portion of the sole a metal stiffening brace o1'support.'n

It is well known among shoemakers that the ordinary metal shank ascommonly used by nailing same to the shank portion of the shoe, althoughlong tolerated is entirely unsatisfactory in turn shoes, by reason ofthe fact that in wear thesole frequently breaks away from the said sharkportion to which it' e 1s fastened or glued.

`I attain the yobjects of my invention as shown in the accompanyingdrawing in which:

Figure 1. is a side elevation partly in section of a shoe equipped withmy invention;

`Figs. -2fan'd 3 are, respectively, a top plan and a side elevation ofthe brace or support; and Fig. 4 is a plan View of the sole proper,indicating the relative position of my brace.

In carrying out my invention, my idea is to form an elongated pocket Bdirectly in the material of the shoe s ole D, one end of said pocketterminating at the under face of the sole above the heel of the shoe andat such an angle as to produce a lip C which closes the entrance to saidpocket after the metallic spring brace A has been forced into thepocket. It will therefore be' readily under. stood that after the heelhas been applied to the shoe the escape of brace A from pocket B will beimpossible.

Having thus fully described my invention, what I claim as new'and desireto secure by Letters Patent is:

The combination with an integral shoe sole having' an elongated pocketformed directly in the material thereof, the forward endof said pocketbeing closed and the rear end of said pocket terminating-at the underface of the sole above the heel of the shoe, of a lip integral with saidshoe sole, said lip being located at the open end of the pocket andbeing adapted to close the entrance to said pocket and a metallic springbrace disposed in said pocket. p

In testimony whereof I have hereunto set my hand in the presence of twoattesting witnesses.
